Last September, General Motors issued a recall for 3.64 million vehicles registered in the U.S. The reason? Software that controlled those vehicles' safety devices--namely, airbags and seatbelt pretensioners--might occasionally slip into "test" mode, which would prevent the devices from being deployed in collisions.
The good news is that most of the vehicles that have been fixed under that recall are working just fine.
The bad news? An internal safety audit has shown that nearly 41,000 vehicles brought in for service might not have been properly repaired. Specifically, the software associated with the airbag sensing and diagnostic module may not have been fully updated.
As a result, the software on those vehicles still stands a risk of slipping into "test" mode, preventing airbags and seatbelt pretensioners from deploying during crashes.
The recall affects the following makes and models:
- 2014-2017 Buick Encore
- 2014-2016 Buick Lacrosse
- 2015-2016 Cadillac Escalade
- 2015-2016 Cadillac Escalade ESV
- 2014-2016 Chevrolet Caprice Police Pursuit Vehicle
- 2014-2017 Chevrolet Corvette
- 2014-2017 Chevrolet Silverado 1500
- 2015-2016 Chevrolet Silverado 2500 HD
- 2015-2016 Chevrolet Silverado 3500 HD
- 2014-2016 Chevrolet Spark EV
- 2014-2016 Chevrolet SS
- 2015-2016 Chevrolet Suburban
- 2015-2016 Chevrolet Tahoe
- 2014-2016 Chevrolet Trax
- 2014-2017 GMC Sierra 1500
- 2015-2017 GMC Sierra 2500 HD
- 2015-2017 GMC Sierra 3500 HD
- 2015-2016 GMC Yukon
- 2015-2016 GMC Yukon XL
The recall affects 40,683 vehicles registered in the U.S. Owners will receive recall notices by mail, asking them to take their vehicles to their local dealerships for service. Dealerships will upgrade the software on the airbag sensing and diagnostic module at no charge. If the airbags on those vehicles have been deployed, they'll receive entirely new modules. GM hasn't yet said when the recall notices will be mailed.
